X-ray fluorescence (XRF)

Definition

X-ray fluorescence (XRF) is a non-destructive analytical technique used to determine the elemental composition of materials by measuring the characteristic X-rays emitted from a sample when it is irradiated with X-rays. This technique is particularly valuable in archaeological studies, as it allows researchers to analyze metals and other materials without causing damage, making it ideal for examining Viking Age weapons and artifacts.
